The effect of joint spacing on the stability of rock slopes reinforced with rock bolts
Journal Title: International Research Journal of Applied and Basic Sciences - Year 2015, Vol 9, Issue 3
Abstract
In this paper, the effect of joint spacing on the stability of rock slopes reinforced with rock bolts was investigated. For this purpose, the rock slopes with different dips in jointed schist rocks were modeled using the Phase2 software and their stability were determined using the critical strength reduction factor (SRF) of slopes. In order to stabilizing slopes, the rock bolts with different angles were installed on the slopes. The results show that by increasing joint spacing, the strength reduction factor (SRF) has been increased and the maximum of SRF in each slope is obtained for the rock bolts perpendicular to the slopes. Furthermore, by increasing dip of slopes, the effect of joint spacing in the strength reduction factor (SRF) is irregular.
